That's right, there's no indication in the 'mt stat' line whether hardware
compression is on or off. But it seems to me that, with my AIT-1 drive,
'mt compression {0|1}' is the way to go. You can test it by writing
similar data to the tape in both compressed and uncompressed modes -- the
throughput should be significantly higher in compressed mode. Paul
Bijnens sent a Perl script to do just this to the list last week. Check
the archives under AIT-1 and tapetype.
